Deutsch ist meine Muttersprache - da ich aber in einem internationalen Umfeld zuhause bin folgendes in englisch:
A results-driven and experienced Chief Technology Officer with a proven track record of developing and implementing successful business strategies. Possesses excellent leadership, communication, and team management skills, with expertise in controlling, software development, and optimizing business processes. Strongly committed to driving organizational growth and delivering outstanding results.
Throughout my career, I have demonstrated proficiency in full-stack software engineering, leveraging the Java stack and AWS cloud services to build scalable solutions. With over 20 years of experience in software development, I possess a deep understanding of complex systems and excel in designing intricate architectures from inception to front-end implementation.
In addition, I have extensive experience in utilizing ReactJS for frontend development, enabling the creation of intuitive and user-friendly interfaces. My passion lies in developing highly scalable and efficient solutions, ensuring optimal performance and a seamless user experience.
Moreover, I have hands-on experience with a wide range of cutting-edge tools and technologies, including Python, TensorFlow, and machine learning algorithms. 2018 – way before chatGPT I successfully developed and implemented a SaaS tool based on machine learning and RPA for automatic messaging in a performance marketing environment. This involved dynamic text generation, image detection, and data extraction. Additionally, I employed RPA Automation and Selenium to automate message sending and answering on various platforms.
As a problem solver and innovative thinker, I thrive on overcoming challenges and finding creative solutions. I consistently demonstrate strong leadership, effective communication, and efficient team management, fostering collaboration and driving successful outcomes.
Overall, I bring a wealth of experience, technical expertise, and a results-oriented mindset to deliver impactful solutions and drive business growth.
